The opposite sides of the parallelogram are congruent given that the

opposite triangles formed by the diagonals are congruent.

Response:

The vertices of the parallelogram in the question is; ABCD

The point of intersection of the diagonals AC and BD is the point E

By proving that ΔABE ≅ ΔCDE, we have;

∠BEA ≅ ∠CED by vertical angles theorem

∠EAB ≅ ∠ECD by alternate angles theorem

The diagonals of a parallelogram bisect each other, therefore;

\(\overline{AE}\) =  \(\mathbf{\overline{EC}}\)  

Therefore;

ΔABE ≅ ΔCDE by angle-side-angle, ASA, congruency rule;

Which gives;

\(\overline{AB}\) ≅ \(\overline{CD}\) by CPCTC

The correct choice is therefore;

Answer:

2 2/5 hours

Step-by-step explanation:

In 6 hours Brian can lay 1 slab of concrete

dividing both side by 6

in 6/6 hours Brian can lay 1/6 slab of concrete

Thus, in 1 hour  Brian can lay 1/6 slab of concrete

In 4 hours Greg can lay 1 slab of concrete

dividing both side by 4

in 4/4 hours Greg can lay 1/4 slab of concrete

Thus, in 1 hour  Greg can lay 1/4 slab of concrete

Thus, total part of slab laid by both in 1 hour when they work together

1/6 + 1/4 = 4+6/(6*4) = 10/24 = 5/12

5/12 of slab of concrete is laid by both of them in 1 hour

time taken to lay 5/12 of slab = 1 hour

dividing both side by 5/12

time taken to  5/12/ 5/12 of slab = 1/5/12 hour = 12/5 hours

time taken to 1/1 of slab = 12/5 hours = 2 2/5 hours

Thus,

it takes 2 2/5 hours to lay the full slab of concrete when Brian and Greg work together,

Answer:

the value of a - b is 4.

Step-by-step explanation:

We have been given the following two equations:

a + b = 10 ------------(1)

a² - b² = 40 -------(2)

We can factor the left-hand side of equation (2) using the difference of squares identity:

(a + b)(a - b) = 40

Substituting equation (1) into this equation, we get:

10(a - b) = 40

Dividing both sides by 10, we get:

a - b = 4

Therefore, the value of a - b is 4.

Step-by-step explanation:

if I understand this correctly :

a + b = 10

a² - b² = 40

(a² - b²) = (a + b)(a - b) = 40

10(a - b) = 40

(a - b) = 4

The mean from a Histogram, table, and dot plot, it is not possible to determine the mean directly from a stem-and-leaf plot.

Out of the given options, the display of data for which it is not possible to find the mean is the stem-and-leaf plot.

A histogram displays data in the form of bars, where the height of each bar represents the frequency of data within a specific range. From a histogram, it is possible to calculate the mean by summing up the products of each value with its corresponding frequency and dividing it by the total number of data points.

A table presents data in a structured format, typically with rows and columns, allowing for easy calculation of the mean. By adding up all the values and dividing by the total number of values, the mean can be obtained from a table.

A stem-and-leaf plot organizes data by splitting each value into a stem (the first digit or digits) and a leaf (the last digit). While a stem-and-leaf plot provides a visual representation of the data, it does not directly provide the frequency or count of each value. Hence, it is not possible to determine the mean directly from a stem-and-leaf plot without additional information.

A dot plot represents data using dots along a number line, with each dot representing an occurrence of a value. Similar to a histogram and table, a dot plot allows for the calculation of the mean by summing up the values and dividing by the total number of data points.

In summary, while it is possible to find the mean from a histogram, table, and dot plot, it is not possible to determine the mean directly from a stem-and-leaf plot.

Answer: 7.5 ounces of  7% acid solution is mixed with 12.5 ounces of 23% acid solution to obtain 20 oz of a 17% acid solution.

Step-by-step explanation:

Let x = Ounces of 7% acid solution

y=  Ounces of 23% acid solution

According to the question , we have two linear equations:

x+y=20    

i.e. y=20-x  ...(i)

0.07 x+ 0.23y =0.17 (20)

i.e.  0.07x+0.23y= 3.4 ...(ii)

Substitute value of y from (i) in (ii) , we get

0.07x+0.23(20-x)= 3.4

⇒ 0.07x+4.6-0.23x=3.4   [distributive property]

⇒ 0.07x-0.23x=3.4-4.6 [subtract 4.6 from both sides]

⇒ -0.16x=-1.2

⇒  x = 7.5    [divide both sides by-0.16]

put value of x in (i) , we get y= 20-7.5 =12.5

Hence, 7.5 ounces of  7% acid solution is mixed with 12.5 ounces of 23% acid solution to obtain 20 oz of a 17% acid solution.

The sentence with proper subject-verb agreement is the student as well as the teacher want to go to the museum. In this sentence, the subject is what we call a compound subject, meaning that the verb refers and agrees with more than just one singular word.

The compound subject is "student" and "teacher" and they are connected by "as well as", which functions as a coordinating conjunction would. That's why the verb should conjugate in its plural form.

Option A is incorrect because the structure inside parentheses is not related to the verb and does not influence its conjugation. Options C and D have a verb in the singular form for a compound subject - that would demand a plural conjugation.

Answer:

\(\rm x=7\)

Step-by-step explanation:

Given equation:

\(\rm 5x-2+x=9+3x+10\)

Collect like terms:

\(\implies \rm 5x+x-2=3x+10+9\)

Combine like terms:

\(\implies \rm 6x-2=3x+19\)

Add 2 to both sides:

\(\rm \implies 6x-2+2=3x+19+2\)

\(\rm \implies 6x=3x+21\)

Subtract 3x from both sides:

\(\rm \implies 6x-3x=3x+21-3x\)

\(\implies \rm 3x=21\)

Divide both sides by 3:

\(\implies \rm 3x \div 3=21 \div 3\)

Answer:

20/9 hours

Step-by-step explanation:

Note: I'm assuming 'upstream' means against the current.

If the boat flows against the current, it's speed is 13 - 4 = 9 mph.

\(\frac{20m}{9mph} =\frac{20}{9} hours\)

That means our answer is 20/9 hours.

If it is travelling with the current, its speed is 13 + 4 = 17 mph.

SR=15units

‹RTQ=90° since ‹RTQ and ‹RTS are supplementary

Given that ‹RTQ is a right angle then RTQ is a right-angled triangle making RQ the hypotenuse

With that knowledge we calculate RT using Pythagorean theorem

RT=√(20)²-(16)²

RT=√400-256

RT=√144=12units

Now for triangle RST, SR is the hypotenuse and should have the longest length whose adjacent,ST should also sum up with 16 to give a number which when combined will give the square root of the sum of the squares of RQ and SR

Plug in 9 for ST and SR becomes

√(12)²+(9)²=√144+81=√225=15 units

This is true because SQ=16+9=25 units

and using Triangle RSQ,

SQ=√(20)²+(15)²=√400+225=√625=25 units

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

The probability of rolling two trick number cubes with the numbers 5, 10, and 15 on them can be calculated using the formula P(A) = n(A) / n(S), where P(A) is the probability of event A, n(A) is the number of favorable outcomes, and n(S) is the total number of possible outcomes.

In this case, the total number of possible outcomes is 6, since there are six possible combinations of two number cubes. The number of favorable outcomes for a sum of 10 is 2, since there are two possible combinations (5 and 5, and 10 and 15). Therefore, the probability of rolling a sum of 10 is 2/6, or one-third. The probability of rolling a sum of 15 is also one-third, since there is only one possible combination (10 and 5). The probability of rolling a sum of 20 is one-sixth, since there is only one possible combination (10 and 10). Therefore, the probability model for the sum of the two number cubes is a 2-column table with 3 rows. Column 1 is labeled Sum with entries 5, 10, 15. Column 2 is labeled probability with entries one-half, one-third, one-sixth.
